The Korg Pitchblack chromatic guitar tuner puts precise tuning and great functionality into a sleek, compact floor unit that's easy to use anywhere. If you play live, you'll appreciate the clear, well-lit display the Pitchblack offers, plus the large footswitch makes it easy to access. Its rugged aluminum chassis is built for the road, as well. The LED meter can be switched between four modes (Meter, Full Strobe, Half Strobe, and Mirror), and true bypass means your tone stays pure as it runs through the practical, convenient Pitchblack.
